ANDREW H. STONE, OF KANSAS CITY, MISSO URI.

Application filed June 12,

To all whom it may concern:

Be it known that I, ANDREW H. STONE, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Extension- Tables,of which the following is a specifi cation.

My invention relates to improvements in extension tables which may beused to advantage in libraries, parlors, dining rooms, or wherever it isdesired to have a table that can be adjusted to occupy a small spaceorextended to give additional capacity when needed.

The table embodies a plurality of foldable leaves which are hingedtogether, so that when not in use they may be folded and supportedunderneath the top of the table, said leaves being at all times attachedto the table to prevent their loss and also to provide a table soconstructed that it may be easily and quickly operated.

' In order that the invention may be fully understood, reference willnow be had to the accompanying drawings, in which:

Figure 1 is an inverted plan view of the table extended.

Fig. 2 isan irregular longitudinal section taken on line IIII of Fig. 1.

Fig. 3 is an inverted plan view of the table folded into compact form.

Fig. 4 is an irregular cross section on line IV-IV of Fig. 3.

Fig.5 is an irregular cross section on line V-V of Fig. 1.

Fig. 6 is a detail perspective view of the extension leaves detachedfrom the table.

Fig. 7 is a fragmentary section on line VII-VII of Fig. 1.

Fig. 8 is an inverted plan view of a modified form.

In carrying out the invention, I employ a frame consisting of adepending rim 2, transverse members 4, and longitudinal members 6. Thetransverse members 4 are secured at their ends to the rim 2, while thelongitudinal members 6 are each secured at their ends to the transversemembers 4 and at one edge to the inner surface of Specification ofLetters Patent.

the rim 2. The transverse members "4 are provided at their undersideswith blocks 8 to which the upper ends of the legs 10 are rigidlysecured.

12 designates a pair of slidable leaves which constitute the table topwhen reduced 1 in the top of the rim 2 to which they are secured bysuitable means such as screws 20, Fig. 5. The hooks 18 overlap the rails14 and coact with guides 22 in holding the leaves 12 in position uponthe rim 2. The guides 22 are fixed to the undersides of the leaves 12 bysuitable means such as screws 23 and slidably engage the under surfaceof the longitudinal frame members 6.

24 designates a pair of foldable leaves adapted to be disposed betweenthe slidable leaves 12 when the table top is extended as disclosed onFigs. 1 and 2, or folded beneath aid'slidable leaves 12 when the tabletop is contracted to the position disclosed on Figs. 3 and 4. Thefoldable leaves 24 are operably connected by hinges26 and one of saidleaves is provided with plates 28 and a bearing 30, which are swiveledupon a rod 32 provided at one end with an arm 34 and at its opposite endwith an arm 36 terminating in a handle 38 arranged close to one side ofthe rim 2 as disclosed on Figs. 1 and 4, so that it can be readilygrasped for a purpose which will hereinafter appear.

The rod 32, which carries the foldable leaves 24 is journaled inbearings 40 secured to the top of the transverse frame members 4.Spacing leaves 41 are interposed between the plates 28 and the adjacentends of the bearings 40, to prevent the extension leaves 24 fromshifting toward either of the transverse frame members 4 and getting outof position to pass between the slidable leaves 12 when the same aredrawn apart to admit said foldable leaves 24. Brackets 42 fixed to theundersides of the transverse frame members 4, coact with the rod 32 insupporting the foldable leaves 24 when in folded position.

Each slidable leaf 12 is provided'with two fixedly mounted stops 44 and45. The stops 44 are engaged by the arms 34 and 36 to lock said slidableleaves 12 in abutting position as disclosed on Fig. 3, while the stops45 hold the edges of the foldable leaves 24 when the table top isextended as disclosed on Fig. 1. The resiliency of the arms 34 and 36enable them to engage the stops 44 and 45 with sufiicient friction toprevent the weight of the handle 38 from rocking the shaft 32 and thusmoving the arms 34 and 36 downwardly and out of engagement with saidstops. The stops 44 also limit the outward'movement of the leaves 12 byabutting the ends of the rim 2.

The foldable leaves 24 are reliably locked in extended position by acatch 48 and a keeper 50, which-latter is fixed to the leaf 24 which ismounted on the rod 32. The catch 48 is mounted on apivot 52 carried by aplate 54 fixed to the rail 2, and said catch 48 is yieldably held inengagement with the keeper 50 by a coil spring 56. The catch 48automatically engages the keeper 50 when the leaves 24 are extended butmust be manually released from said keeper 50 before the leaves 24 canbe folded. A slot 60 is provided in one of the frame members 6 to allowthe keeper 50 to engage the catch 481 In practice when the table top isto be extended the handle 38 is grasped and swung downwardly todisengage the arms 34 and 36 from the stops 44. The leaves 12 are thenslid outwardly in opposite directions to each other until the stops 44contact the rim 2. The foldable leaves 24 are then swung upwardly on therod 32 and unfolded to rest uponthe rim 2 where they are secured by thecatch 48 and the keeper 50. The leaves 12 are then slid toward eachother until they abut the adjacent edges of the leaves 24, against whichthey are reliably secured by swinging the handle 38, upwardly to engagethe arms 34 and 36 with the stops 45.

In the modified form disclosed by Fig. 8, the construction and operationof the parts are like those disclosed on the preferred form, the chiefdifference being that a bail.

38" is substituted for the handle 38. The bail 38 is longer than thehandle 38 and hence can be more readily found with the hand when thearms 34 and 36 are to be engagedor disengaged from the stops 44* and45*. The ends of the bail 38 are rotatably mounted in plates 28*, eachof which has two bearings 29 instead of but one bearends of the bail 38are prevented from mov ing apart by nuts 31 threaded upon said ends andabutting the adjacent bearings 29.

From the foregoing description, it will be readily understood that Ihave provided an extension table embodying the advantages ,above pointedout, and while I have shown leaves operably connected and arranged tofold beneath said slidable leaves when the same abut or be extendedbetween said slidable leaves when the same are slid apart, stops on theslidable leaves, and a rod rockably mounted onthe frame and providedwith means for engaging certain of the stops to lock said slidableleaves in abutting position and engage the other stops to lock theslidable leaves in extended position.

2. In a table of the character described, a frame, legs to said frame,slidable leaves mounted on said frame to slide apart or abut each other,foldable leaves operably connected and arranged to fold beneath saidslidable leaves when the same abut or be extended between said slidableleaves when 7 the same are slid apart, a rod on which the foldableleavesare rockably mounted, bearings on the frame in which said rod ismounted, brackets secured to the frame and which coact with said rod insupporting the foldable leaves in .folded position, and spaced elementson each slidableleaf to coact with the rod in securing the slidableleaves in extended or abutting positions.

3. In a table of the character described, a frame, legs to said frame,slidable leaves mounted on said frame toslide apart or abut each other,two parallel rails associated with grooves in the under sides of theslidable leaves, hooks secured to the frame and projecting into thegrooves to overlap said rails, foldable leaves operably connected andarranged to fold beneath said slidable leaves when the same abut or beextended between said slidable leaves when the same are slid apart, arod on which the foldable leaves are rockably mounted, bearings on theframe in which said rod is mounted, brackets secured to the frame andwhich coact with said rod in supporting the foldable leaves in foldedposition, and spaced elements on each slidable leaf to coact with therod in securing the'slidable leaves in extended or} abutting positions.

4. In a table of the character described, a frame, legs to said frame,slidable leaves mounted on said frame to slide apart orabut each other,foldable leaves operably connected and arranged to fold beneath saidslidable leaves when the same are slid apart, a rod carrying thefoldable leaves and rockaably mounted on the frame, arms on said rod,and two members spaced apart on each F.
